Lenoname , why not trying this: class Person: def __init__(self, name, age, sex): self.name = name self.age = age self.sex = sex def __str__(self): return f"{self.name}, {self.age}, {self.sex}" def __repr__(self): return f"{self.name}, {self.age}, {self.sex}" #Initialize an instance of the object: A = Person("John", 34, "Male") personList = [] print(A) # this uses __str___ personList.append(A) print(personList) # this uses __repr__

Lenoname , this is an explanation from the official python documentation: object.__repr__(self): called by the repr() built-in function and by string conversions (reverse quotes) to compute the "official" string representation of an object. object.__str__(self): called by the str() build-in function and by the print statement to compute the "informal" string representation of an object.

You just have an indent problem of your code inside your class.

class Person: def __init__(self, name, age, sex): self.name = name self.age = age self.sex = sex #Initialize an instance of the object: A = Person("John", 34, "Male") personList = [] personList.append(A) print(personList) Just edited the tab before "def __init__" and then pushed each rows, then it's fine.

It works : [<__main__.Person object at 0.7fd4696b8550>] is a normal output, it says that you are printing an Person object inside a list type.
